    • An ignition apparatus for an internal combustion engine can be produced at low cost and small size by preventing the generation of a spark at a spark plug due to a turn-on voltage with a simple ignition coil construction having no energy loss. The apparatus include an ignition coil having a primary coil and a secondary coil, a spark plug to which a high voltage from the secondary coil is impressed, and a coil driver for driving the ignition coil. The coil driver has a switching element for controlling the primary current, an IC for driving the switching element, and a turn-on voltage prevention circuit inserted between a secondary coil low-voltage side terminal and ground. The turn-on voltage prevention circuit is composed of a parallel circuit comprising a diode in the form of a bare chip and a thick film resistor, and is mounted on the same substrate together with the IC.
    • 通过以简单的不具有能量损失的点火线圈结构的导通电压来防止火花塞产生火花,可以以低成本和小尺寸制造内燃机点火装置。 该装置包括具有初级线圈和次级线圈的点火线圈,来自次级线圈的高电压的火花塞和用于驱动点火线圈的线圈驱动器。 线圈驱动器具有用于控制一次电流的开关元件,用于驱动开关元件的IC和插入在次级线圈低压侧端子和地之间的导通电压防止电路。 导通电压防止电路由包括裸芯片形式的二极管和厚膜电阻器的并联电路组成,并且与IC一起安装在同一基板上。

    • The present invention relates generally to a simple, low cost ballast for fluorescent lamps that incorporates an integrated circuit and a number of ballast protection functions to cost effectively enhance its reliability. End of lamp life circuitry is provided to shut down the ballast when rectification currents due to lamp aging exceed a predetermined level. This circuitry also functions to stop the ballast operation when the lamp's voltage exceeds a predetermined cutoff level for a set period of time. Re-ignition circuitry is provided that restarts the ballast when new lamps are installed without shutting off the ballast. Multiple striking attempt circuitry is provided that initiates a predetermined number of striking attempts such that cold or old lamps are quickly ignited without the introduction of excessive flickering.
    • 本发明一般涉及一种简单,低成本的荧光灯镇流器,其结合了集成电路和多个镇流器保护功能,以有效地提高其可靠性。 提供灯寿命电路的结束,以便在由灯老化导致的整流电流超过预定电平时关闭镇流器。 该电路还用于在灯的电压超过预定的截止电平达一段时间时停止镇流器操作。 提供重新点火电路,当新灯安装而不关闭镇流器时重新启动镇流器。 提供了多个触发尝试电路,其启动预定数量的醒目尝试,使得冷或老灯快速点燃而不引起过度闪烁。
